Equation for circumference is c = 2(pi)r

r = 1/2(d)

d = 20

So…. r = 1/2(20) = 20/2 = 10

Going back to circumference equation

c = 2(pi)(10) = 2(3.14)(10) = 62.8

Answer:

<h2> A - 62.8</h2>

Step-by-stexplanation:

The formula for circumference is C=2πr

  • C (circumferece) divided by 2 equals your r (radius) wich is 10
  • plug in 10 for R use the following formula (c=2πr) to get your answer
  • you should get 62.83185 which rounds to 62.8

Your welcome :)

V = Ah

where:

V = Volume of prism

A = Area of uniform cross-section or base of prism = 96 inches^2

h = Perpendicular height of prism = 9 inches

Substitute the values given in the question into the formula.

V = 96 × 9

V = 864 inches^3

What is the value of x?
pickupchik [31]

The angles are congruent meaning that you can set them equal to each other:

26 = 5x + 11

Now you can solve for x

26 - 11 = 5x + (11 - 11)

15 = 5x

15/5 = 5x/5

x = 3

Hope this helped!

A baseball player has made 32 free throws in 45 attempts for current success rate of 71%. How many consecutive free throws must
s344n2d4d5 [400]

Answer: The player need to make 2 consecutive free throws to raise the average to 75%.

Step-by-step explanation:

Let the number of extra consecutive free throws to raise the average to 75% be 'x'.

Number of free throws already taken = 32

Number of attempts = 45

According to question, it becomes,

\dfrac{32+x}{45}=0.75\\32+x=45\times 0.75\\\\32+x=33.75\\\\x=33.75-32\\\\x=1.75

Hence, the player need to make 2 consecutive free throws to raise the average to 75%.
